Hello folks , 

First of all I want to thank the Code Blocks team for their valuable effort  , so thank you for making code blocks a great IDE 

 .

You probably know that there is a template for making Qt applications in Code Blocks but unfortunately errors of the type "Undefined reference to vtable" or something like that are generated when you use custom slots , this bothered me a little bit since I've been using CB for about 4 years and I'm very familiar with it  , so I decided to make my own "solution".

Anyway , here is how I fixed the problem : 

After opening CB , go to Tools -> Configure Tools then click at Add , choose a name for your new tool  I simply called it MOC , specify the absolute path to moc.exe . Now the hardest part , in Parameters put the following line :

Code:

${ACTIVE_EDITOR_FILENAME} -o  moc_${ACTIVE_EDITOR_STEM}.cpp

ACTION_EDITOR_FILENAME is a macro that contains the file name of the currently active file and ACTIVE_EDITOR_STEM contains the same file name but without file extension.

Finally , in the 'Working directory' field , put ${PROJECT_DIR} and click Ok.

Now that our newly created tool is installed , how are we going to use it ? 

Well , just create your Qt project using the template shipped with CB , as usual , now  let's say you have a class called MyClass that contains custom slots , open MyClass.h then run the tool this will generate something like moc_MyClass.cpp , include it into MyClass.cpp and the work is done 

 .

I hope this little tutorial is useful .

Thank you for reading.
